Publication (UPOL): Iron-Oxide-Supported Ultrasmall ZnO Nanoparticles: Applications for Transesterification, Amidation, and O-Acylation Reactions
Abstract An efficient maghemite-ZnO nanocatalyst has been synthesized via a simple coprecipitation method, where ZnO nanoparticles are uniformly decorated on the maghemite core and characterized by XRD, SEM-EDS, ICP-AES, XPS, TEM, HRTEM, and Mossbauer spectroscopy; maghemite nanoparticles are in the typical size range 10-30 nm with ultrasmall (3-5 nm) ZnO nanoparticles. A competent and benign protocol is reported for various organic transformations, namely, transesterification, amidation, and O-acylation reaction in good to excellent yields (75-97%) using magnetically separable and reusable maghemite ZnO nanocatalyst.
